Bulding a motor? Wiseco is proven to make some of the best pistons on the market! Featuring valve pocket designs that allow maximum flow around valve, also allowing oversized valves ang high lift cams to be utilized and piston crown shapes designed to promote maximum intake charge efficiency thru scavenging mixture "cross flow" during intake and exhaust valve overlap. More fuel and air equals more horsepower! Their pistons are designed to optimize squish or quench during compression combustion cycle event, resulting in resistance to detonation and pre-ignition. The end product is longer engine life and increased horsepower potential.

great product and customer service

I bought these pistons during the black friday sale from Dan. He hooked me up with an unbeatable price on these. If you ever need anything I suggest you go to MAP and get your parts there. Thanks again. Can't wait to install them. :)

The best pistons for your 4g63

Curt Brown Racing shortblock built to his tolerances and coupled to a set of Manley Turbo Tuff I beams for a rock solid daily driver and weekend warrior.. These pistons will without a doubt take anyone to their goals and beyond without any issues with reliability. These are as good as it gets for your 4g63 and with multiple compression ratios, stroker lengths their should be a pistons for just about anyones build. If not call them and I'm sure they can work with you to meet your needs.
